NWS Denver/Boulder, CO wrote its last area forecast discussion before the first event at Jul 31, 9:38 AM MST, 1 hour 22 minutes earlier. Its key messages:
Area Forecast Discussion National Weather Service Denver/Boulder CO 1038 AM MDT Wed Jul 31 2024 .KEY MESSAGES... - Hot and dry weather continues, with elevated fire weather conditions across the higher terrain today into early this evening. - Continued hot through early next week with mostly dry conditions Thursday and Saturday. Better chance for precipitation Friday and then again early next week with locally heavy rainfall possible. && .UPDATE... Issued at 1030 AM MDT Wed Jul 31 2024 The winds have continued to be very light on all of the fires this morning. Light easterly winds will continue through the rest of the day over the fires. The other concern today will be elevated to near critical fire weather conditions across the eastern plains, east of a line from Fort Morgan to Simla. Winds have gusted above 30 mph this morning but the winds are expected to relax this afternoon and turn more northeasterly. Therefore, Red Flag Warnings were not issued. The rest of the forecast remains on track. && .SHORT TERM /Today through Tonight/... Issued at 327 AM MDT Wed Jul 31 2024 It's been a busy overnight due to fires. Overall there has been some weak convection over the far nern plains where better low level moisture resides. In addition, the srn portion of an upper level trough, that is moving across the nrn Rockies, is helping as well. Appears some of this activity may linger through sunrise. Meanwhile, the upper level trough will move into the nrn High Plains later today with mainly dry westerly flow in the mid levels. Thus, with limited cape and a dry airmass it doesn't appear there will be any convection this aftn or tonight. At the surface, a cold front was already moving across the plains this morning. This front will bring in some minor cooling, however, highs may still reach the mid to upper 90s over most of nern CO. Meanwhile, HRRR model shows smoke covering most of the CWA later this morning thru tonight so expect hazy skies. && .LONG TERM /Thursday through Tuesday/... Issued at 327 AM MDT Wed Jul 31 2024 Hot temperatures are expected through the period as upper level high pressure remains over the Rocky Mountain Region. Mostly dry weather and smoky skies are expected on Thursday with only a few high based gusty showers and storms over the high country and areas south if I- 70. Some of the hi res models, especially the NAM 3KM, are showing some stronger convection with heavy rain over portions of the Palmer divide, while other models such as the HRRR show no QPF. My feeling is that the stronger convection will stay to the south of our CWA where better moisture resides. However, will need to keep an eye on forecast trends for this area over the next 24 hours. On Friday, models are hinting at some increase in low level moisture east of the mountains as winds shift to a southeast. This combined with a weak upper level disturbance moving in from northwest, may lead to a better chance for afternoon and evening showers and storms across the forecast area. With PW's ranging between 0.70" to 1.00" across the Foothills, plains and Palmer Divide, some of the storms could produce brief moderate to heavy rain. Precipitation chances and QPF are expected to decrease on Saturday as drier air behind the upper level disturbance moves into the CWA from the northwest. The upper ridge is progged to flatten and elongate Sunday into early next week. This may allow some subtropical moisture to flow into Colorado from the southwest. Initially, this should result in an increase in shower and thunderstorm activity across the high country with mostly dry conditions on the plains. However, models are showing the activity spreading onto the plains by early next week as low level moisture and PW's increase. Consequently, locally heavy rainfall could be possible with some of the storms. && .AVIATION /12Z TAFS through 12Z Thursday/... Issued at 517 AM MDT Wed Jul 31 2024 Winds were north at DIA early this morning and should stay in that general direction thru 18z. By 18z they will become more ENE and stay that way thru 01z. After 01z they will become more east and then change to SE by 07z. VFR conditions today and tonight, however, should see smoke into the area later this morning and continue thru tonight. Visibility should be 6 miles or above. && .FIRE WEATHER... Issued at 327 AM MDT Wed Jul 31 2024 Elevated fire conditions will continue across the area today with low humidity levels and dry conditions. Winds should stay mainly below Red Flag criteria over the higher terrain. However, if somewhat stronger mid level flow were to mix down, then winds could end be slightly stronger than forecast mainly over North Park, the nrn Foothills and mtn areas north of I-70. && .BOU WATCHES/WARNINGS/ADVISORIES...
